Configures a route map filter for a neighbor.
| remoteaddr | Specifies the IPv4 or IPv6 address of a BGP neighbor. The switch uses the IP address format to determine if the address is an IPv4 or IPv6 address. |
| all | Specifies that the configuration applies to all neighbors in the specified address family. If no address family is specified or if an IPv4 address is specified, the configuration applies to all IPv4 neighbors. If an IPv6 address family is specified, the configuration applies to all IPv6 neighbors. |
| ipv4-unicast | Specifies the IPv4 unicast address family. |
| ipv4-multicast | Specifies an IPv4 multicast address family. |
| ipv6-unicast | Specifies the IPv6 unicast address family. |
| ipv6-multicast | Specifies an IPv6 multicast address family. |
| vpnv4 | Specifies the VPNv4 address family for Layer 3 VPN support. This address family is applicable for PE to PE BGP neighbor sessions only. This keyword may prompt warning or error messages if executed for a regular BGP neighbor session, or for a PE to CE neighbor session. |
| in | Specifies to install the filter on the input side. |
| out | Specifies to install the filter on the output side. |
| none | Specifies to remove the filter. |
| policy | Specifies a policy. |
If no address family is specified and an IPv4 address is detected, IPv4 unicast is the default address family.
This command applies to the current VR or VRF context.
The policy can be installed on the input or output side of the router. The policy is used to modify or filter the NLRI information and the path attributes associated with it when exchanging updates with the neighbor.
Note
A policy file applied to BGP neighbors cannot have NLRI for both IPv4 and IPv6 address families defined in the same policy file.
If you do not specify an address family, this command applies to the IPv4 unicast address family. To apply this command to an address family other than the IPv4 unicast address family, you must specify the address family.
Note
For an IPv6 peer, an IPv6 address family must be specified, because an IPv6 peer does not support IPv4 address families. If no address family is specified for an IPv6 peer, the default, the IPv4 unicast address family, applies and the command fails. Similarly an IPv4 peer only supports IPv4 address families and the command fails if an IPv6 address family is specified.
To configure this feature on Layer 3 VPNs, you must configure this feature in the context of the MPLS-enabled VR; this feature is not supported for BGP neighbors on the CE (VRF) side of the PE router.
The following command configures the route-policy filter for a neighbor based on the policy nosales:
configure bgp neighbor 192.168.1.22 route-policy in nosales
This command was first available in ExtremeXOS 10.1.
This command required a specific license in ExtremeXOS 11.1.
Support for IPv6 was added in ExtremeXOS 12.6 BGP.
Support for Layer 3 VPNs was added in ExtremeXOS 15.3.
This command is available on platforms that support the appropriate license. For complete information about software licensing, including how to obtain and upgrade your license and which licenses support the BGP feature, see the ExtremeXOS and Switch Engine 31.7 Feature License Requirements document.
